Re: [Pharo-dev] the return of the strange methods

by ClÃ©ment Bera

They may be useful. Imagine you are too lazy to create a subclass of Error, but not lazy enough to create a test and copy paste a String. Then you write in your method: self error: 'some strange error happened' And you can test it: self shouldnt: [ "some strange code" ] raise: Error whoseDescriptionIncludes: 'some strange error happened' description: 'the strange error did not happen ! That's strange' Seriously, as you saw these methods are used only in their tests. I guess you can remove them.

How is GlorpOpenDBXDriverPoolingDriver supposed to work?

by Mariano Martinez Peck

Hi guys, There is something I don't understand. The idea with GlorpOpenDBXDriverPoolingDriver is that it takes care of opening the connections and have a pool, right? Now...I am at the glorp side...each time I want to do something I instantiate a GlorpSession. Of course, I don't want to send #login to this session because that's what the pool would do if necessary. So say I just send a query with the session. I get a DNU because 'databaseDriver' is nil. As you can see, databaseDriver is set in PharoDatabaseAccessor >> loginIfError:. of course, if I send #login or #loginIfError before doing the query the pool "works"...but...I am opening a connection for each query. So I don't understand how this is supposed to work. How should I manage my Glorp sessions with this pool? Thanks, -- Mariano http://marianopeck.wordpress.com

[ANN] Amber 0.11.0 released!

by Nicolas Petton

Amber 0.11.0 released! * About the release Three months have passed and we are happy to announce the release of Amber 0.11.0! Some numbers about this release: 433 commits by 13 committers, increasing the number of core committers to 25. 50 unit tests were added to the kernel, bringing us to 313 unit tests in total. Since the last release 60 issues were closed, bringing us to 499 issues closed. This release includes a lot of bug fixes, improvements to the CLI, as well as a preview of the next IDE, named Helios. Amber now also uses a CI server [1]. To try the Helios, the new IDE, open the helios.html page, or evaluate in any other amber page `amber.loadHelios()`. The compiler also received some improvements, especially regarding message send optimisations and super sends. Here's the list of commits and closed issues: https://github.com/amber-smalltalk/amber/commits/master https://github.com/amber-smalltalk/amber/issues?direction=desc&sort=updated… There is a lot more to come with Helios, a stepping debugger based on the AST is in progress and currently in the 'debugger' branch on GitHub. * Installing Amber from NPM To install amber from NPM, run npm install amber * Migration from Amber 0.10.0 Amber compiled code should be compatible with Amber 0.10.0, but recompiling is needed in order to get contexts working: Compiler new recompile: (Package named: 'MyPackage') classes. (Package named: 'MyPackage') commit * API changes 0.11.0: * AnnouncementSubscription use #valuable: instead of #block: (deprecated) * AbstractCodeGenerator inherits from Object, not NodeVisitor * Object>>printString * replace >>printString with >>printOn: * replace >>storeString with >>printString * PackageLoader is now PackageHandler (>>commit: >>setupPackagenamed:prefix: >>ajaxPutAt:data: * Package>>fetch: is now Package>>load: * Package>>fetch:prefix: is now Package>>load:prefix: * Queue>>front replaced by Queue>>next * Queue>>frontIfAbsent: replaced by Queue>>nextIfAbsent: * Queue>>back: replaced by Queue>>nextPut: * smalltalk.addMethod() does not use explicit JS selector * JSObjectProxy>>canForwardMessage: replaced by use of JSObjectProxy>>lookupProperty: with asJavaScriptSelector * JSObjectProxy>>forwardMessage: replaced by explicit JSObjectProxy>>forwardMessage:withArguments: * String>>asJavaScriptSelector moved to Kernel-Objects package + Object>>asString + Object>>putOn: + String>>isVowel + Collection>>putOn: + CharacterArray>>putOn: + Stream>><< + Stream>>write + SequenceableCollection>>newStream + SequenceableCollection>>readStream + SequenceableCollection>>stream + SequenceableCollection>>streamClass + SequenceableCollection>>writeStream + Collection>>isImmutable + Stream>>nextPutString: + StringStream>>nextPutString: + JSStream>>nextPutClassRefFunction: + String>>crlfSanitized + inlined Block now also responds to >>value: + Parser: split literal into runtimeLiteral and parseTimeLiteral + Parser: write #(4 #(5 6 #()) 7) as #(4 (5 6 ()) 7) + Parser: write #(#on:do: #Object) as #(on:do: Object) + Parser: Symbols for binarie selectores + Package>>commit + AIContext>>initializeLocals + ASTInterpreter>>withBlockContext: + smalltalk.allSelectors() + Object>>isCompiledMethod + Object>>isPackage + Object>>isBehavior + ClassMoved Announcemen class + Behavior>>includesBehavior: + Environment>>classes + Environment>>allSelectors + Environment>>removeProtocol: + Environment>>renameProtocol:to:in: + CompiledMethod>>protocol: + Smalltalk>>globalJsVariables + Smalltalk>>addGlobalJsVariable: + Smalltalk>>deleteGlobalJsVariable: - Object>>storeOn: - Object>>log:block: - Object>>printNl - Compiler-IR.st >>javascriptSelector - Compiler-IR.st >>nextPutVar: - Kernel-Collections.st >>asSuperSelector - Collection>>readStream - Collection>>stream - Collection>>streamClass - Collection>>writeStream - Symbol class (replaced with String) - IRInlinedNonLocalReturn class - IRInlinedSend>>nonLocalReturnInliner - IRNonLocalReturnInliner class - Package>>dependencies - Package>>dependencies: - Package>>properties - Package>>jsProperties - Package>>jsProperties: - Package>>propertiesAsJSON - Package>>propertyAt: - Package>>propertyAt:ifAbsent: - Package>>propertyAt:put: - Browser>>ajaxPutAt:data: We hope you join us in developing Amber and having fun!

What I ment with many ways of implementing this is because I have seen the pool at different levels: VWPoolingDatabaseAccessor -> Glorp's DatabaseAccessor level GlorpOpenDBXDriverPoolingDriver -> Glorp's PharoDatabaseAccessor DatabaseDriver level XXX custom pool that stores/retrieves GlorpSession -> at application level So...anyone? > > Thanks, > > -- > Mariano > http://marianopeck.wordpress.com > -- Mariano http://marianopeck.wordpress.com

Has anyone used a connection pool with glorp and postgres native driver?

by Mariano Martinez Peck

Because I need this and I have some ideas. There are many way to implement this (integrating Glorp and the native driver for this) that I would like to see if someone already did something. So...anyone? Thanks, -- Mariano http://marianopeck.wordpress.com
